I only know of two places to find the VIN:
* Stamped on a metal plate attached to the top front of the driver's side door frame.
* Stamped on top of the left (driver's side) frame rail, near the steering gear. However, this stamped number may only contain the sequential serial number.
You can decode the VIN at one of the following web pages: http://www.americanclassic.com/paint.htm
